INSIGNIA 55-inch Class F50 Series LED 4K UHD Smart Fire TV with Alexa Voice Remote (NS-55F501NA26)

Excellent TV
Great TV and for the price I got it for (169.99$ marked down from 299.99$ for black Friday sales), it was absolutely worth it. The picture is very clear and the sound is great. My room is not too big and and not too small, and the 50″ screen is perfect size for my room. Easy to set up and connect to online services. Streaming capability is great, as it has many streaming apps you just download. I love this TV and recommend it to anyone looking for an affordable 4K tv

Was what I wanted a basic and inexpensive TV.
This TV is great for how much it cost. I Caught a good sale. Easy setup after I got it out of the box. . This 55 inch replaced my old 32 inch Insignia that was about 15+ years old. It still works and is now livinging in my Bedroom.I wanted a basic TV. Not all the bells and whistles. Something that is easy and clear to look at. Sound: is good. Without a sound bar.The Fire TV, I was familiar with.So it was any easy operating system, too use..

Purchased in Nov. 2025. SO MANY problems. Detailed Review. Do NOT buy!
I have 2 other Insignia TVs that I purchased in 2020. Neither is a FireTV – Just regular TVs and they work great – still. I was looking for a larger TV and I had zero reservations about buying Insignia again. I was hugely surprised that I had an absolute miserable experience to set it up and later, watch. Problem 1: Wouldn’t connect with remote. Contacted Amazon via chat. Was told to unplug TV. Didn’t work. Unplugged again. Didn’t work. Unplugged modem and router. Connected to remote. Problem 2: Wouldn’t play Amazon Prime. Called this time. Spoke to first Amazon rep for over an hour. Got disconnected. Called back. Another hour. The guy couldn’t recommend anything other than what the first Amazon guy said which was to disconnect my router and modem, unplug the TV and try again. The TV gets to a screen that says it “needs an update.” Click on it to start the update which takes forever and then the TV restarts on its own and returns you back to the original blacked out “apps” that it is supposed to support (you can’t see them, but they are supposedly there). Tried several times, and it kept going through the same cycle of “needing an update, waiting for 45 min for the cycle, restarting TV.” Problem 3: Amazon phone rep asks for serial number which I read to him from a photograph I took of the back of the TV. He says it’s invalid. What I read to him clearly says “Serial Number” plus it had a manufacture date of June 2025. He asked me to send him the photo as he couldn’t validate the serial number. I also gave him my Amazon order number. He said the photo shows another serial number – smaller and way less obvious – with a manufacture date of 1 year earlier (2024!) than the larger, central label with the “invalid serial number.” What’s going on with that Amazon? Are you slapping on a year younger serial number and manufacture date to make the TV look newer and not like it’s one that has been in your store room for over a year? I bought the thing 24 hours ago. Problem 4: There is no user manual. Problem 5: The power cord hole to plug in is hidden with absolutely no reference on any of the 2-page pamphlet where it is located on the back of the TV. Other reviewers have mentioned this. If I didn’t read a customer review, I never would have found the power connector. It’s vertical! There’s an indentation on the left side of the TV as you are facing the back. Hidden at the top of it (it’s totally concealed – feel with your finger for it) is the input for the electric cord. Problem 6: Once started – there’s still the issue of it going thru different screens with rectangles of the supposed apps it has all blacked out so you can’t see which app it is. No icons. Problem 7: When you finally get it to work and see the apps – and let’s say you choose a movie on Amazon Prime – if you put it on “pause” and leave the room to get a snack , the TV will turn itself off. When you turn it back on you won’t see the movie, but instead the home screen with all the apps. When you choose “Amazon Prime Video” to get your movie – the thing doesn’t even show you the movie at this point. You have to use the search function to find said movie. The only saving grace is that when you find the movie, it does let you resume from where you left off. Other reviewers have noted that there is no setting to avoid the heavy lifting of trying to find your movie again. The auto shut-off engages to “save power” according to the other reviewers. I haven’t experienced it shutting off while I’m watching a movie – only when I put it on “pause.” As others have said, the interface is super sluggish. It takes a while to load whatever app you choose. Unless you enjoy wasting your life in the set up process (I cannot understand how folks say it’s “easy” to set up – and I am pretty tech savvy), I wouldn’t recommend buying this TV. I, myself, am going to watch it daily for the next 2 weeks to see if it starts having the screen issues that others reported. In this way my return window is still open. BTW – TV size is measured on the diagonal. Some reviewers have measured the length of the TV and reported an incorrect size. Also don’t be fooled by the $169 “sale price” or “cyber Monday” or “Black Friday” or whatever title is given to the price. The price is and was $169 for the 50″ TV for a while (just go to “price history” and you can see it for this and any product sold on Amazon). Hope that helps all of you considering this set. If I had to do it over again, I’d suggest another manufacturer.
